“Tempel heads the nation’s first school of philanthropy and there wouldn’t be one without his decades of dedication to the concept of learning about giving," the publication wrote. "Even though he’s slated to retire soon, he’ll still be around the sector pushing for new ideas powered by research and accumulated knowledge.”

Tempel has been selected for The NonProfit Times “Power and Influence Top 50” list 13 times since it debuted in 1998. In 2013, the publication named him its inaugural “Influencer of the Year,” selecting him for the honor from among the nonprofit leaders nationwide who comprised the 2013 “Power and Influence Top 50.”

The 2014 honorees have been invited to a September gala in Washington, D.C. The list is compiled by The NonProfit Times’ staff and people from the philanthropic sector.
